IMPROVEMENTIN FEED-WATER APPARATUS FOR STEAM-BOILERS.

Specification forming part of Letters Patent No. 10,695, dated March 2S, 1854.

To all whom it may concern:

Be it known that I, BENAIAH FITTS, of the the city and county of Worcester, and State of Massachusetts, have invented a new and useful Machine for Feeding Steam-Boilers, called an Automatic Feederf7 and l do hereby declare that the following is a full, clear, and exact description ol' the construction and operation of the same, reference being had to the annexed drawings, making a part of this specieation, in which- Figure l is an end view; Fig. 2, a front View; Fig. a vertical section of the valve-box and valve; Fig. 4, a transverse section through m .12, and Fig. 5 a section through y z,the same letters referring tothe same parts in all.

'l he machine consists of two reservoirs, as A N. Fig. 2, with tubes B B' B" B lattached, leading to valve-box C, through which openings ale made for the passage of steam and water, also one Vopening' into pipe D, leading to reservoir E, tilled with wire gauze or other ready conductor ot' heat, through which a passage is left through the central part more open than the rest; or the pipe may be of suiicient size and lilled to answer for the same purpose; the reservoir E to be connected to the .supply ot' cold water at F or other convenient place. The reservoirs are surinounted with one or more turns ota chain or Wire, one end of which is attached to some part of the reservoirs or iinlnovably fixed and the other attached to lever G. The valve H and its box or seat C lareinade of a conical form, or nearly so, so that the expansion of the same will not prevent a perfect t, and admit of the triction being relieved by the set-screw o, made. pointed for a center for the valve to turn on. The valve H is so formed that a passage may be open from l5 to B,entirely shut oft' from the rest, and B and B be closed, and when the valve is turned toward N the steam may pass through B' into N, and a passage from D through to B, and when the valve is turned toward A the steam may pass through B into A and a passage open from D through B into N, the other openings not mentioned being shut. The valve H having a stem or arm attached and connecting with lever G, whose fulcrum so arranged to give proper motion to the valve to shift the passages, as described, the chain is provided B into N, (the chain so arranged as to slack on the left hand of lever G and tight on the right,) and heating and expanding it, thechain render-ing Will-draw the lever, and turn the valve, and shut ofr'the steam, and open the passage through the body of the valve, and allow the steam to pass into A and partially condense,and,turning alittle more,open the passage through B to D. The steam Willcondense into the Water or reservoir E and the water flow into and fill or nearly ll N, While the steam passing into A will heat that and reverse the motion of the valve, N contracting by the condensing and filling with water, and, on the valve turning so as to open the passage B', the steam passes into the reservoir, displacing the water, allowing it to run down through B and I into the boiler, the machine continuing its action so long as steam is admitted at I and Water at F.

What I claim as new, and desire to secure by Letters Patent, in feeding apparatus for steam-boilers, is

The arrangement ofthe steam and water chambers, chains, pipes, and valves, constructed and operated as and for the purposes herein BENAIAH FITTS.

,set forth.
